Agentic Harness Matters More Than Models: Big Finance AI Boost
eyishazyer · x · 2026-08-06
The comment highlights that in practical AI applications, the agentic harness is becoming as important as the underlying model itself.
In the finance sector, for example, Primer achieved a score of 79.1% on BigFinanceBench (a 928-question finance benchmark) by leveraging an agentic architecture. In contrast, the underlying model alone (referred to as GPT-5.5 in the post, likely a typo) scored only 55.8%. The benchmark tests AI's ability to perform real financial analyst tasks such as retrieval, calculations, modeling, and reasoning.
